| AT5G23720 | PROPYZAMIDE-HYPERSENSITIVE 1 (PHS1); FUNCTIONS IN: protein tyrosine/serine/threonine phosphatase activity, phosphoprotein phosphatase activity; INVOLVED IN: cortical microtubule organization, regulation of gene expression, response to abscisic acid stimulus, regulation of stomatal movement; LOCATED IN: cytoplasm; EXPRESSED IN: 25 plant structures; EXPRESSED DURING: 15 growth stages; CONTAINS InterPro DOMAIN/s: Zinc finger, C2H2-like (InterPro:IPR015880), Dual-specific/protein-tyrosine phosphatase, conserved region (InterPro:IPR000387), Dual specificity phosphatase, subgroup, catalytic domain (InterPro:IPR020422), Protein kinase-like domain (InterPro:IPR011009), Protein-tyrosine phosphatase, active site (InterPro:IPR016130), Actin-fragmin kinase, catalytic (InterPro:IPR015275), Dual specificity phosphatase, catalytic domain (InterPro:IPR000340); BEST Arabidopsis thaliana protein match is: dual specificity protein phosphatase 1 (TAIR:AT3G23610.2); Has 35333 Blast hits to 34131 proteins in 2444 species: Archae - 798; Bacteria - 22429; Metazoa - 974; Fungi - 991; Plants - 531; Viruses - 0; Other Eukaryotes - 9610 (source: NCBI BLink). dual specificity protein phosphatase family protein Encodes a protein tyrosine phosphatase Propyzamide-Hypersensitive 1 (PHS1). One of the mutant alleles, phs1-1, is hypersensitive to the microtubule-destabilizing drug propyzamide, suggesting that PHS1 may be involved in phosphorylation cascades that control the dynamics of cortical microtubules in plant cells. A second allele, phs1-3, is hypersensitive to abscisic acid, indicating a possible involvement of PHS1 in ABA signalling. | 5 | + | View |
